越过松林,远处有一座小花园。那裡青草长得又长又茂盛,铁杉花像洁白的星星一样闪耀,夜莺整夜唱歌。牠整夜歌唱,冰冷的月光俯瞰着牠,紫杉树张开巨大的枝干,庇护着沉睡的人们。

Far away beyond the pine-woods, there is a little garden. There the grass grows long and deep, there are the great white stars of the hemlock flower, there the nightingale sings all night long. All night long he sings, and the cold crystal moon looks down, and the yew-tree spreads out its giant arms over the sleepers.
